Taal?, whom it may concern:

13e it known that I, JOSEPH MELZER, a citi- '/.en of the United States,residing at Cleveland, inthe county of Cuyahoga and State of Ohio, haveinvented new and useful Improvements in a Combined Electric-Arc Lamp andFan, of which the following is a specification.

My invention relates to improvements in combined electric-arc lamps andfans, and pertains to an electric lamp provided with a surrounding motorfor driving,preferably, a fan, all of which will be full y describedhercinafter and particularly pointed out in the claims.

The primary object of my invention is to provide a combined electric lamp and electric motor, the motor preferably constructed to drive a fan,whereby a lamp and a fan are carried by the same hanger or support.

Another object of my present invention is to provide an electric-lamphanger with a motor surrounding the carbon tube or hanger and the fieldand armature of the motor supported thereby, whereby a lamp and fan arecombined in one to be used separately or together, as desired. i

Another object of my invention is to provide an electric lamp with asurrounding motor-iield supported thereby and a motorarmature track alsosupported by the hanger, the motor-armature adapted to receive fana-rms,whereby a combined fan and lamp or lamp and motor is provided andcombined.

A further object of my invention is to provide a combined lamp and motorand a switch and electric connections between the switch, the motor, andthe lamp, the switch so constructed that either the lamp or the fan maybe used alone or both at the same time, as may be desired.

. In the accompanying drawings, Figure 1 is a vertical central sectionalview of a combined arc-lamp and motor embodying my invention. Fig. 2 isa similar View with parts of the lamp and hanger omitted, showing amodification in the bearing for the motor-armature. Fig.

3 is a detached enlarged View of the switchlever. Fig. 4 is adiagrammatical view showing the switch and electric connections betweenthe switch, the motor, and the lamp.

Fig. 5 is an enlarged sectional view of a portion of the adjustingmember for primarily adjusting the limit of downward movement of theupper carbon of the lamp.

Referring now to the drawings, 1 indicates a lamp hanger or support, and2 a tube connected therewith and depending therefrom, carrying at itslower end a plate or disk 3. Surrounding the lower portion of this tube2 is the winding 4,' forming the magnet of a solenoid, the tube 2 at itslower portion forming the usual' hollow core of the solenoid.Surrounding the upper portion of the tube 2 is the usual rheostat orresistance for the solenoid Ll. Situated within the tube 2, at its lowerportion, and surrounded by the solenoid is a brass tube (3, carrying atits lower end an iron tube 7, which is the armature of the solenoid. Thelower end of' the tube 2 is spread out or enlarged, as shown at 8, toform an opening suflicient-ly large to receive the armature 7 and aspring 9 thereabove. The spring has its upper end engaging the upper endof the enlarged portion 8 of the tube 2 and its lower end engaging theupper end of the armature 7, whereby the spring 9 normally forces thearmature downward. The tube G receives the upper carbon 10, which isadapted under norm al conditions to move freely therethrough. 'lheoperation, construction, and arrangement of a carbon-feeding mechanismwill be described hereinafter.

A depending tube 11 has its upper end turned outward, as shown at 12,and this upper portion of the tube 1l is suitably clamped to the plate3, an insulating material 14 being placed therebetween to insulate thetube 11 from the plate 3. Screwed within the lower end of the tube 1l isthe lamp-globe socket 15, adapted to receive the screwthreaded socket 16of the globe 17. The lower end of this globe 17 is provided with ascrew-threaded socket 1S, adapted to receive a screw-threaded plug 19,and this screwthreaded plug 19 is provided with a carbon- 95 ICO socket2O at the lower end of the globe, by means ot' which a current iscarried to the lower carbon 2l. A cup-shaped motor-support 25 has ascrew-threaded central opening 2G, which screws externally upon thelower end of the tube ll and is supported thereby. The tube ll in turnis supported by the plate 3 and the plate in turn by the tube 2, whichis supported by the hanger l, whereby the motor-support is held by thelamp-hanger. The side or vertical wall 27 of the cup-shaped support Q5is provided with the motor-held 2S, which is arranged in series. Anannular motor-armature 29 is arranged, preferably, in series upon a ring30, the said ring 30 constructed with the portion Sl to receive thewindings of the armature and with an upwardly-extending annular ange 32,which carries the comm utator Supported by the plate are thecommutator-brush supports 34. l here show the commutaton brushesconsisting of spring-actuated copper pencils or rods 35, which engagethe commutator 33, the comn'ultator-brushes being' electricallyconnected in the usual or any desired manner for receiving the currentfrom the main line.

In Fig. l I show thepreferred form of bearings for the motor-armature,which is in the form of a ball-bearing, the bottom oi' the cupsllapedsupport 25 being provided with a ballrace' 257 and the ring 50 with aball-race 3S, the balls 3*.) being situated therebetween and serving tohold the armature in position as it rotates around the lamp-socket.Projecting from and supported by the ring 30 are a plurality of arms 40,which are U-shaped in side elevation, as shown, having at theirouterendshorizontally-prejecting sockets 4l, adapted to receive thefan-arms 42.

lt will be noted that the motor-field 2S is situated outside of themotor-armatures, and preferably in this form, though it will be readilyconceived that this arrangement may be reversed, the main object beingthe supporting of the motor-field and armature by the lamp andsurrounding it, whereby a combined lamp and motor are provided, themotor preferably for driving a fan.

'lhe plate 3 carries the projecting contacts 45, and the plate to at thetop ofthe solenoid carries an adjustable screw-threaded rod 47,insulated from the plate t6 and through which electricalconnection ismade through the contact 4S, which passes between the contacts t5. Thisconstruction is for the purpose of having the contact t8 between thecontacts t5 when the plate f3 has been screwed to its normal positionupon the lower end of the tube 2.

The mechanism for feeding the carbon consisls of the solenoid et, itsarmature 7, the spring than d a spring dependingarm 50, which has itsupper end attached in any suitable manner to the brass tube 0 and itslower portion extending along parallel with and outside of the armatureZand its lower end provided with an inwardly-projecting clutch portion5l, adapted to engage the carbon lO below the armature. This spring-arm50is provided with an iron portion 53, which forms an armature adaptedto be attracted bythe solenoid-armature 7 when the latter is magnetized.In operation when the eurrentis wea-lt` cned the arm 50 will springoutward and release the carbon, permitting it to drop, and when thecarbon has dropped and the current sufficiently strong the armature 7will immediately be drawn upward, and at the same time the arm 50 isattracted by the armature 7, causing its clutching portion 5l to engagethe carbon and to thereby draw the carbon up against the tension of thespring il. The tension of the sprinOr 9 is such as to hold the carbon ata proper point for a proper arc, and thus the carbon is fed as desired.The amount of downward movement permitted the armature 7 is regulated bythe rod 55, which has its lower end passing through the plate 3 andturned inward under the armature, as shown. The upper end of the rod 55passes through a tube 56, carried by the plate sl-G, and its extremityis screw-threaded to receive a thumb-nut 5S, whereby it may be raisedand lowered for regulating in the first instance the armature fall. rlhetube 56, as illustrated in Fig. 5, is provided with a platinum screw 59,engaging a groove (SO, formed in the rod 55 and through whichelectricalcontact is made, as will be readily understood by those skilledin theart. The object of the groove is to hold the rod against any turning orlateral movement..

The switch-lever 71y is pivoted to the under side of the cup-shapedmotor-support 25, as illust ated in Fig. l, and in Fig. Sthe specificconstruction of this lever is shown. This switch-lever is provided withthe insulated spring-contactly, having two arms, as illustrated, andadapted to engage the plates c, which are insulated one from the other,and also from the switch-plate U2. The lever is also provided with aspring-actuated contact ml and with a second contact Also carried by theplate G2 are the contact-points g, e, and s.

The electrical connections will now be de scribed in a description ofthe operation of the switch for either throwing in the circuit the lamp,or the fan alone, or both. lVhen the fau alone is thrown in, the lever his moved to carry the contacts f in engagementwith the contacts c, thusmaking electrical connection between these contacts, and the eurrent isthen from the main line to the wire u b, contacts c and f, and the wired to the motor and p and j to the other pole of the main line. lVhen thelamp alone is to be operated, the lever 7L is moved to carry the contactG3 to the contact e, and the current passes through o, lever 7i, contacte, wire to the clutch, through the carbons, and to the wire j. lVhenboth the lamp and fan are in operation, the lever 7L is moved stillfarther IOO llO

in the direction indicated by arrow and the y contact f in engagementwith the contacts c,

the contact m in engagement with the contact g, and the contact 63 inengagement with the contact s, when both the fan and motor circuits willbe closed, as will be readily understood.

My invention is especially intended for indoor service, whereby a lam-pand a fan may be combined in one and either or both used, as desired. Inthe winter season, when the fan is not in service, the fan-arms, ifdesired, may be detached from the motor-armature arms 40 or they may beleft thereon, as desired.
